As promised, I'll try to get round to as many of the posts as possible. I must admit, though, that the quality of the contributions is below what I would have expected from AAM contributors based on my past experience. It is clear, sadly, that many of the posters have not actually read what I've written, as evidenced by the fact that no-one has answered my challenge from earlier this morning to tell me where they disagree with what I actually wrote as opposed to what they think I wrote.
Despite that, I'll soldier on - for now anyway. In future, I'll think twice before posting anything on AAM. The quality of discussion is far better on other forums. Maybe it's because they read what I actually wrote.
I don't know where to start. Let's try by looking at Table 1 of my paper, and try to use that to address some of the questions raised.
This table shows that, if the scheme started on 1 January 2020, with cash flows increasing from 10 in month 1 to 20 in month 2, 30 in month 3, etc. (probably not far off how the pattern of actual cash-flow roll-outs might look like), then monthly smoothed returns vary from a low of +0.13% to a high of +0.33%. Monthly market returns, by contrast, vary from a low of -15.1% to a high of +4.9%.
The problem is that a "smoothed" value of a fund is fine in theory but impossible to implement in practice. Everyone knows that financial markets fluctuate and are prone to prolonged optimism and pessimism. The problem is that where we are in the cycle is only clear in a decade's time and you have to make a drawdown tomorrow. I've been in a job where making policy depended on estimates of where we were the financial cycle and trust me it was really hard. Endless discussion about models and an impossibility of explaining them to people who made decisions.
Let's look at the above table in the light of
@NoRegretsCoyote 's comments.
"Everyone knows that financial markets fluctuate". It's not often that they have fluctuated more than they did in the first few months of 2020, as the world came to grips with the financial impact of Covid19, yet the formula comes up trumps. "
The problem is that where we are in the cycle is only clear in a decade's time and you have to make a drawdown tomorrow". When the smoothing formula was calculating the smoothed return for (say) March 2020, it didn't have a clue where in the cycle we were. I still don't know. It didn't have to know. All it required to know how to calculate any month's smoothed value were three things: 1. That month's market value; 2. The previous month's smoothed value; 3. The assumed long-term rate of return, which I've taken as 4% a year for all periods. It won't vary much from that in the long-term, unless there's a severe bout of inflation at some stage. The actual long-term return assumed is not a significant factor in determining returns, especially when the scheme is more mature.
"
and you have to make a drawdown tomorrow" Let's assume that the net cash flow of 30 in March in the above table is 50 of gross inflows and 20 of gross outflows. The 20 who "made a drawdown tomorrow" got the smoothed value, which was significantly higher than market value. The excess over market value was paid for by the 50 gross who came in at that price. You can then ask: why were the 50 prepared to join at that inflated price? The answer is that, taking a long-term perspective, they could reasonably expect to earn smoothed returns in future like those shown above for the first six months of 2020. That gave them the confidence to stay in equities for life, including in the run-in to retirement and all through their retirement years. That peace of mind confers massive extra value and is well worth the cost of paying a bit over market value from time to time. On average, though, they know that, over their entire working lifetime and throughout their retirement, they will get - and receive - market value on average.
That table also helps to answer
@nest egg 's comments about the Vanguard Balanced Fund.
If I had access in my pension to invest in say Vanguard's Global Balanced Fund, would I get more or less the same benefit as Colm's approach? A smoothed return.
I think that the term "balanced" in the fund's title refers to the fact that it has a mix of equities, bonds, and maybe some alternative assets. It does not refer to its performance. It would be interesting to compare its performance in the first six months of 2020 with the figures in the above table for smoothed and actual returns. I would be prepared to bet that its performance was very close to the unsmoothed returns e.g., a massive fall in value in March 2020. If you were invested in that fund and were due to retire at the end of March, you wouldn't feel very balanced. However, you would be more than happy if you were one of the 20 (netted from the 50 gross) under my smoothed approach who got out that month, having seen their fund grow by 0.13% in the month. Out of interest,
@nest egg , could you get the actual numbers for me for the Vanguard Balanced Fund for those six months?
The second problem is that Colm's proposal seems to depend on pooling of current and future pensioners' funds.
I don't understand what the problem is here. The net cash flows of 10, 20, 30, 40, 50, 60 in months January to June 2020 in table 1 are the net result for active contributors (positive) and pensioners (negative). Of course, in that six months, the numbers of pensioners will be tiny, given that the fund only started in January, but you get the point. It doesn't matter a fig whether members are active or pensioners. Both groups are credited with exactly the same returns of +0.29% (Jan), +0.23% (Feb), etc.
OK, that's my lot for now. I may return to that same table to answer others' questions.
